Question

Choose the decimal (s) from the brackets which is (are) not equivalent to the given decimals:
$25.1(25.01,25.10,25.100,25.001)$

Answer 1

There is no value of $0$ after added to right hand side of last digit of decimal.

So, $25.1=25.10=25.100=25.1000=\mathrm{25.1000...}$

But $0$ added in between two digits changes value of number

$\therefore 25.1\ne 25.01$ and $25.1\ne 25.001$

So, $25.01,25.001$ are not equivalent to $25.1$
